Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional battery technology is used to increase energy storage capacity, then the energy density is improved, but the weight and size of the energy storage system increase significantly
Solution Approach 1:
The patent applies parameter changes by transitioning from traditional battery chemistry to dielectric energy storage, fundamentally changing the energy storage mechanism from electrochemical to electrostatic. This enables high energy density without the weight penalty of traditional batteries, as the dielectric material can store energy at much higher voltage levels (2,000V+) without the mass associated with battery components.
Solution Approach 2:
The patent utilizes composite materials in the form of multilayer dielectric structures combining different ceramic materials with complementary properties. These composite dielectric layers achieve high energy density through synergistic material properties while maintaining a compact, lightweight form factor compared to traditional battery systems.
2Use of energy by moving object
If traditional battery technology is used to extend driving range, then the energy storage capacity is improved, but the recharge cycle life remains limited
Solution Approach 1:
The patent changes the fundamental operating parameters from electrochemical reactions to electrostatic field storage, enabling the system to withstand over 500,000 recharge cycles. The dielectric material does not undergo degradation from chemical reactions, allowing for extreme cycle life while maintaining high energy storage capacity.
3Productivity
If traditional capacitor technology is used to achieve rapid charging, then the charge speed is improved, but the energy storage capacity remains insufficient
Solution Approach 1:
The patent employs composite multilayer dielectric structures that combine high-permittivity materials with optimized geometry, achieving both rapid charging capability and high energy storage capacity. The layered composite structure enables fast energy uptake while storing significantly more energy than conventional capacitors.
Solution Approach 2:
The patent transitions from planar capacitor geometry to three-dimensional multilayer stacking, dramatically increasing the energy storage capacity while maintaining rapid charging characteristics. The vertical stacking of multiple dielectric layers multiplies the energy storage volume without increasing the footprint.
4Stress or pressure
If traditional battery technology is used to provide high voltage, then the operating voltage is improved, but the system complexity and weight increase
Solution Approach 1:
The patent changes the voltage generation mechanism from series connection of multiple battery cells to a single high-voltage dielectric energy storage device. This achieves 2,000V+ operating voltage with simplified system architecture, eliminating the complexity of battery management systems, cell balancing, and modular assemblies required for high-voltage battery packs.
